For an introduction that supplies both academic and primary information, I'd suggest John Scheid's An introduction to Roman religion and Robert Turcan's The Gods of Ancient Rome. Additionally, there's also Adkins' Dictionary of Roman Religion and the two volumes of Religions of Rome, of which the second is a sourcebook, so that gives you an abundant amount of information taken from multiple primary sources in just one volume.
I am currently reading Cyril Bailey's Religion of Ancient Rome, which deals primarily with the religion of Numa. Next up is Cato's De Agri Cultora. Maybe Horace later on, or Gellius. Ovid's Fasti also has good information on holidays.
